JMX and Oracle's Application Server

Hello,
I am building a new EJB application and wanted to add logging support to it via Log4j (which I was considering doing using JMX). The EJB application must be deployable on both Oracle's application server and JBoss- (all development centers around Jboss now). Looking through the Log4j list archives it was recommended that the "loggers" be retrieved from JNDI. To get the loggers into JNDI and facilitate runtime configuration, I was considering using JMX (MBean) to set things up. Will my proposed solution work on Oracle's application server?
Thanks

Auditing in oracle 10g database and oracle 10g application server

Dear friends,
We have oracle 10g application server and oracle 10g database server in place.My criteria is to audit users connected using oracle application user credentials to the database.
Can you please tell me how can i do it.
Thanks & regards,

Its the database connection you want to track. The session audit will show where it came from.
Auditing is turned using this command:
alter system set audit_trail = DB scope=spfile;
Note: The use of spfile will require a DB bounce before audit starts
To audit Sessions:
audit create session;
Query by Audit Type:
SELECT A.USERNAME,
OS_USERNAME,
A.TIMESTAMP,
A.RETURNCODE,
TERMINAL,
USERHOST
FROM DBA_AUDIT_SESSION A
WHERE USERHOST = <replace with iAS servername> ;
By User
SELECT USERNAME,OBJ_NAME,ACTION_NAME , TIMESTAMP
FROM DBA_AUDIT_TRAIL WHERE USERNAME = 'SCOTT';
Check for users sharing database accounts
select count(distinct(terminal)),username
from dba_audit_session
having count(distinct(terminal))>1
group by username;
Attempts to access the database at unusual hours
SELECT username, terminal, action_name, returncode,
TO_CHAR (TIMESTAMP, 'DD-MON-YYYY HH24:MI:SS'),
TO_CHAR (logoff_time, 'DD-MON-YYYY HH24:MI:SS')
FROM dba_audit_session
WHERE TO_DATE (TO_CHAR (TIMESTAMP, 'HH24:MI:SS'), 'HH24:MI:SS') <
TO_DATE ('08:00:00', 'HH24:MI:SS')
OR TO_DATE (TO_CHAR (TIMESTAMP, 'HH24:MI:SS'), 'HH24:MI:SS') >
TO_DATE ('19:30:00', 'HH24:MI:SS');
Attempts to access the database with non-existent users
SELECT username, terminal, TO_CHAR (TIMESTAMP, 'DD-MON-YYYY HH24:MI:SS')
FROM dba_audit_session
WHERE returncode <> 0
AND NOT EXISTS (SELECT 'x'
FROM dba_users
WHERE dba_users.username = dba_audit_session.username);
Other audits you might consider:
audit grant any object privilege;
audit alter user;
audit create user;
audit drop user;
audit drop tablespace;
audit grant any role;
audit grant any privilege;
audit alter system;
audit alter session;
audit delete on AUD$ by access;
audit insert on AUD$ by access;
audit update on AUD$ by access;
audit delete table;
audit create tablespace;
audit alter database;
audit create role;
audit create table;
audit alter any procedure;
audit create view;
audit drop any procedure;
audit drop profile;
audit alter profile;
audit alter any table;
audit create public database link;

Oracle 10g application server installation and configuration

Dear All,
i am going to install oracle 10g application server including forms & report services.
what is the latest version for oracle 10g application server so that i download and install the correct one.
please put URL to download the software .
Thanks & regards,
Sher khan

hi,
for forms and reports purpose you can download standalone oracle forms and reports (version 10.1.2.0.2) component.
If you want to upgrade it you can upgrade it to 10.1.2.3.0.
find url for the same :
http://www.oracle.com/technetwork/middleware/ias/downloads/101202-095224.html
i'll recommend you to use oracle fusion middleware 11g forms, reports,portal and discoverer component.

Hi
You have to deploy Servlet as a WAR File. I hope you already have web.xml file which u can get automatically in eclsipse during creation of servelet. I am not sure what ide u r using here. If u have created servlet in eclipse then I would suggest create a project dynamic webproject if u have not where IDE create all required files autmatiicaly and even you can deploy application from there itself.
If you wanted to deploy manually then follow below steps (if u have war file)
I am assuming you already created a Weblogic Domain and have admin username/password. Start your domain. Login into weblogic console like http://host:port/console and use admin username/password. Then from Deployments section, deploy the above WAR file. In Weblogic you can deploy JAR (EJBs, java files), WAR (web jsp, html, webservices, servlets) or EAR (JAR + WAR). In your case its just a WAR file.
Thanks

Queries related to Oracle 9i Application server

I have some queries related to JDBC and oracle 9i Applcation
server.
1. Does JDBC Driver supporting VAX/VMS comes with the Oracle 9i
App
Server?
2. What JDBC Driver is supported for Oracle 9i Application
Server?
3. Is the JDBC Driver Platform Independent?
4. Can we separate OC4J Servlet engine(Web Container) from
Oracle 9i Application
server and put it on a different machine?
5. What other Servlet engine is compatible with Oracle 9i
Application server?
and finally ...
we are developing application with Oracle database in Sun
Solaris 2.8 OS
and after development we have planned to change the oracle
database to
VAX/VMS OS , Will there be any deployment issue because of OS
inconsistency.
Please reply me asap.It will be greatful to you.We are looking
for answers for a very long time.
Thanks

In Oracle 9 Application Server can we create multiple instances???

Hi I need one help this is regarding to the oracle 9 application server in this can we create the multiple instances??
my application was already developed and currently it is working with one instance for this i need to create the another one more instance which is same as existing and my application is web application developed in Forms6i and the db is oracle 9i my requirement is to create one more instance what are all the configuration files need to be modified and please give this info ASAP....

It is still not very clear. What do you mean by creating "one more instance of the same application in the same application server"? By "application" do you mean another instance of OC4J in same Application Server Instance? If yes, you can do that. I mean you can create another OC4J component in same Application Server Instance without doing another installation. Refer this for details:
http://download.oracle.com/docs/cd/A97329_03/core.902/a92171/config.htm#1010793
If you are looking to create another Application Server Instance out of same installation/binaries (i.e. Oracle Home) than the answer is no. You can not create multiple Application Server Instances out of one Oracle Home. You will have to do another installation in a different Oracle Home and that's how you will get another Application Server Instance.
Hope this helps.
Thanks

Installation of Oracle 10g Application Server in custom port or 1522

I want to install Oracle 10g Application Server in Port 1522 or some other port as in port 1521 Oracle 10g database server is already installed.
But every time I try to install Oracle 10g Application Server it give the warning about 1521 port and then start installing on same 1521 port automatically.
What should I do if I want to install in some other port ?
Please help
Thanx

As a method, to install an OAS on a custom port,
1) make a file called staticports.ini and define your components/ports there.
2) on the Specify Port Configuration Options screen, select Manual and specify this file.
Follow this link for details for 10g.
http://download.oracle.com/docs/cd/B14099_19/win.1012/install.1012/install/reqs.htm#CHDJACIG
However, there are ways to use the same port for OAS and DB depending upon the version of your listener. Check the version of your DB Listener, and if it is 10.1.0.2 or higher then you are just good to go with automatic port assignments.

Oracle 9i Application Server+Oracle 8i EE+ Forms on the web Very urgent

Hi,
I have correctly install Oracle 9i Application Server and Oracle 8i Entreprise Edition on Windows 2000. What are the following steps to follow in order to run a form on the web. example: test.fmx?
Thanks in advance.
null

If your web server is working and the forms server is running type:
http://ip addr:port/dev60html/runform.htm
You need to put the ip address or name of your server in and the port number apache is running on (leave blank if this is 80).
This gives you the Oracle Forms start screen.

Deploying Forms with Forms6i/Oracle Internet Application Server 8i - need help!

Hi Gurus!
I am trying to setup the Oracle Internet Application Server 8i (Release 1.0)and deploy the forms to the web. The server is on Solaris. I have installed and configured the application server. I used the 'runform.htm'and 'test.fmx' to test the installation of the application server on the Server machine. In that case it works fine and shows the message 'Application Server is up and running'. Where as if I tried to access the same 'runform.htm'and 'test.fmx' from another client machines through a web browser it is not executing the 'test.fmx' and throws the following error:
" FRM-92060:Failed to connect to the Server. Bad machine specification:'hostname':9001"
Details...
oracle.forms.engine.RunformException:FRM-92060: Failed to connect to the Server.
I am using the default port#9001 to run the Forms server (i tried using another port and i got the same error). The web server is listnening on the port 7777.
I am not sure what needs to be fixed. Can someone please through some light on this?
Thanks!

The Oracle 8i jvm component (formerly known as JSERVER) was designed to support server side java.
This component was initially developed and included in the Oracle 8i rdbms 8.1.5.
Enhancements continued to be implemented with the 8.1.6 and 8.1.7 releases
IAS uses the same oracle 8i JVM from the rdbms to support java code on the middle tier.
Here's how the IAS version and the RDBMS version match up on the Oracle 8i jvm's features.
RDBMS 8.1.6 with IAS 1.0.0 (unix) / 1.0.1(NT)
RDBMS 8.1.7 with IAS 1.0.2 (new name IAS 9i)
8.1.6 / IAS 1.0.0 / IAS 1.0.1 supports :
session EJB's(1.0 spec), corba objects and java stored procedures
8.1.7 / IAS 1.0.2 (aka IAS 9i) supports :
The 8.1.7 implementation will support the 8.1.6 features listed above plus the ejb 1.1 spec (entity ejb's -- see below), servlets and java server pages.
note : in another thread Mr. Devin clarified the current status of the EJB 1.1 spec (entity beans)in the 8.1.7 solaris release and the future win nt release.
If I remember correctly, Mr. Devin reported a last minute issue has delayed the support for the entity bean feature but ejb spec 1.0 / 1.1 session beans are in place.
When the entity bean issue is resolved, a software patch needed to support the entity bean feature will be provided in a rdbms patch.
for additional technical info, please review :
http://otn.oracle.com/products/oracle8i/pdf/8iR3_nfs.pdf

i hope this helps ...

Oracle 9i Application server installation problem(MSG:Fully qualified domain name)

I have installed Oracle 9i database.Now downloaded application server 9iAs,when i am installing I have got this error message(J2ee and web cache)
Message begin
Installation has detected that a fully qualified hostname has not been specified for this host.Oracle 9i application server requires a default domain name to be specified for each host where it is installed .Please consult your OS instructions for details on assigning a default domain name If u are not using DNS server then the file d:\windows\system32\drivers\etc hostsmust also include a line of a form

Message End
Could some one suggest the procedure to follow.
Pl ,mailme to [email protected]
I appriciate your help
Tahnq
Ravi

Search this forum for answers and discussions.
Basically, your machine will need a "fully qualified hostname" e.g. myhostname.mydomain.com, only myhostname is not enough.
Also, AS does not allow the IP to change after install e.g. no DHCP (dynamically allocated IP) allowed!

If you are installing into Windows 2000, one workaround recommendation by Oracle for this problem is:
Install the latest Windows* 2000 Service Pack patch: http://www.microsoft.com/windows2000/downloads/
Create a temporary directory on your Intel PentiumÂ® 4 processor server (e.g. \TEMP).
Copy the contents of the Oracle* Server CD to the temporary directory created in step 2.
Search the directory structure created in step 2 for the existence of the filename SYMCJIT.DLL.
Rename each copy of the SYMCJIT.DLL to SYMCJIT.OLD.
Run the SETUP.EXE from the \TEMP\install\win32 directory and install Oracle 8.1.x.
If you have any other questions on this work around, please contact Oracle.

Migrating applciation from weblogic to oracle 9i application server(OC4J)??????

Hi,
I am migrating my ejb application from weblogic to oracle 9i application server.What changes are needed to be made in code and what configuration changes are required.
In my application i use a couple of session beans wherin a session bean calls the method of the other session bean which acceses the database.I am using a jdbc thin driver for the database connection. is it possible for a session bean to call a method of another session bean which access the database??This concept works well in weblogic where the current application is running.
The problem is that while migrating the application to the orion server, it gives an OrionCMTException ...
memory leak..etc.
Could any one clarify.
Thanks in advance!!!

Hi Avi and Harrison,
Cease Fire avi!!!!.First of all let me clear the issue of posting the same problem twice.Well, when i mentioned the problem the first time , i found the title session bean deployment was not right and few people would look into it as it was a common problem so i thought it would be appropriate if i mentioned the title correctly , so i posted the query again with the change in title.
Now coming to the answer for ur questions.
The platform used is MS Windows NT.
The (OC4J) version is 1.0.2.2.1.
I am not using JDeveloper.
The database is oracle 8i and i am using the thin driver.
The beans to be deployed are stateless session beans.
The client involved is a web client i.e a jsp application.
The first session bean is as follows.
import java.sql.Connection;
import java.sql.Statement;

But if the DBUTILITY session bean is changed to a simple bean and accessed the code works fine and i am able to retrieve the data.Is the problem there because u one session bean cannot access a database connection method from another one or could it be because of the driver???
I hope i am clear.Please revert back in case any more references are needed.
Thanks in advance!!!!!!
